Techno economic simulation model of power grid investment considering demand side resources and transmission and distribution price

Abstract

With the deepening of market-oriented reform of power system, the investment planning of power grid is affected by many factors. According to the actual business process of power grid investment planning, on the basis of traditional power grid planning ideas, the introduction of system dynamics analysis tools will establish a feedback relationship model for many factors related to power grid investment planning, such as economy, security, demand side resource (DR), transmission and distribution price, and carry out simulation calculation, which can provide a reference for making reasonable policy recommendations for power grid investment. The results show that grid companies can adjust their investment plans by themselves in order to meet the grid reliability and under the incentive of the government's transmission and distribution price policy. the adjustment of transmission and distribution price has the inherent characteristics of decreasing volatility, which can be more obvious when reducing the reliability requirements.
